>>2448291I have had the same issues because of sexual traumas. Honestly there's no quick fix, you have to accept that he has done a lot of damage to you and it will take time to build that up. But it should be your top priority to build your self-worth back and love yourself. This is your root issue and things like not wanting to dress up, being shy, losing libido are only symptoms. Also, lacking self-worth puts you at risk of being abused once again.
The easiest thing I did to fix that issue seems kinda silly but it worked quickly : I just told myself things like "I love myself, I look good, I feel good, I'm confident, I feel grateful" while staring at myself in the mirror, atleast once a day. After a week or two my brain automatically spurs positive thoughts when seeing my reflection, instead of the usual "I look tired today, I have a huge pimple, I don't even wan't to go out". In the same vein, when I'm anxious before a social interaction, I'll repeat in my heads encouraging things like "I'm a confident, nice person, and others enjoy my company". It may sound stupid but you probably already do this with negative thoughts, and those negative thoughts have shaped your perception of yourself with enough repetition and time - the goal is to reverse that process.
Pair that with something more engaging but that you won't regret: find a sport you like, yoga, going to the gym, running, stretching or whatever. Something that will make you feel great in your body and proud of yourself. Really stick with something, even if it's just a few minutes a day. It's not an instant fix but just a month of daily activity will make you feel better about yourself, guaranteed.
Just take care of yourself in general, body and mind. Say nice things to yourself. Act like you're a mom taking care of an hurt child, so be gentle and patient with yourself. Change will come in time but you will not go back to who you were before, you'll be an even stronger and better version of yourself. This guy doesn't hold any power over you anymore, you have the power and will to grow out of this and reclaim your love back. Good luck nona, I believe in you.
